D5739715} (facebook/folly@

Add new unit-tests for `constexpr_min` and `constexpr_max` to avoid silly mistakes like this in the future.
It was defined recursively in terms of `constexpr_max` rather than, as intended, in terns of `constexpr_min`. HT Mandar12.

Extract non-portability constexpr math functions to new header
Summary:
[Folly] Extract non-portability `constexpr` math functions to new header.
This new header, `folly/ConstexprMath.h`, is specifically for compile-time-computable math functions. We start with `min`, `max`, `abs`, and `log2`.
Included substantive changes:
* Add new tests for `constexpr_strlen`, which remains in the portability header.
* Make `constexpr_min` and `constexpr_max` variadic.
* Make `constexpr_log2` tail-recursive, remove `const_log2` in `FixedString.h`, and move the related comment.

Don't use symbolizer on OSX
Summary:
When trying to build with targets files on OSX, I couldn't use the symbolizer because it needs StackTrace, which requires libunwind and elf. This makes it so that we only build on linux for now. This also makes it so that we set FOLLY_USE_SYMBOLIZER in autoconf, since that wasn't set before.
Does a few things surrounding usage of the symbolizer library:
- Introduce FOLLY_USE_SYMBOLIZER in folly-config.h and USE_SYMBOLIZER as an AM definition
-- Filter some code out of init and some other random libs that optionally need the symbolizer
- Fix libdwarf detection. Previously on a fresh ubuntu container, we didn't find libdwarf/dwarf.h, so we stopped trying before looking at dwarf.h

Dynamic MPMCQueue: Eliminate cases of enqueue indefinite blocking and failure in the extensible version that impossible under the default pre-allocated version
Summary:
Currently under the extensible version (Dynamic == true), some enqueue operations may block indefinitely or fail (return false) even though such outcomes are impossible under the default (Dynamic == false) pre-allocated version.
This diff eliminates such cases by changing the algorithms for the extensible version. Some of the high-level changes:
- The offset formula for an expansion guarantees that no enqueue operation left behind in a closed array does not have an existing dequeue operation that unblocks it. The old formula was 1 + max(head, tail). The new formula is max(head, current offset) + current capacity.
- Conditional operations validate state after the success of CAS.

Added a for_each function to iterate through ranges
Summary:
Adding a for_each function that allows generalized indexed and breakable iteration through ranges, these can either be runtime ranges (i.e. entities for which std::begin and std::end work) or compile time ranges (as deemed by the presence of a std::tuple_length<>, get<> (ADL resolved) functions)
The function is made to provide a convenient library based solution to the proposal p0589r0, which aims to generalize the range based for loop even further to work with compile time ranges
A drawback of using range based for loops is that sometimes you do not have access to the index within the range. This provides easy access to that, even with compile time ranges.
Further this also provides a good way to break out of a loop without any overhead when that is not used.
A simple use case would be when using futures, if the user was doing calls to n servers then they would accept the callback with the futures like this
auto vec = std::vector<std::future<int>>{request_one(), ...};
when_all(vec.begin(), vec.end()).then([](auto futures) {
folly::for_each(futures, [](auto& fut) { ... });
});
Now when this code switches to use tuples instead of the runtime std::vector, then the loop does not need to change, the code will still work just fine
when_all(future_one, future_two, future_three).then([](auto futures) {
folly::for_each(futures, [](auto& fut) { ... });
});

Drop jemalloc specific smartRealloc integration
Summary:
This was added several jemalloc versions ago, and is no longer a win.
From microbenches in folly/test, this codepath is successful less than .5% of the time.
There are a handful of other places directly using this (fbvector, IOBuf, ThreadLocal),
but should probably change them individually.

Remove a use of SFINAE in the Range constructor.
Summary:
Specifically, the constructor `implicit Range(Iter)` is now declared and defined for all `Range` specializations. It is an error to use it, and we `static_assert`, unless `Iter` is `char const *` or `char *`.
Performance effect
---
Measuring compilation-time on a file that just make ~40k StringPieces, compiled with -O3. All compilers produced identical code before/after this change.
* clang-trunk: 4% improvement
* gcc-5: no change
* gcc-4.9: 11% improvement
* gcc-7.1: 5% improvement
Could this possibly break any existing code?
---
Yes. If you have a function that's overloaded for both `Range<char const*>` and `Range<X>` and your input object is not `char const*` and is implicitly convertible to both `char const*` and `X`: that is now ambiguous whereas before it would unambiguously pick the `Range<char const*>` overload. I don't consider this scenario likely.
Why should this work?
---
Using SFINAE is more expensive at compile time (with some compilation environments) than not using it. It's necessary to use SFINAE when there is an alternative function which will be used in preference when the substitution fails, but when that is not the case it is on average cheaper to make the function always exist and use static_assert to disallow the bad uses of it. A bonus is that the caller gets a more comprehensible error message.

[Folly] Let `MacAddress` use a helper hex-table.
The table is in the `folly::detail` namespace so it is non-public to users of folly, but the rules may not be quite as strict in at least some cases within folly.
Also the helper `unhex` function that this replaces is not `clang-format`-clean, so this lets us sidestep that.
